Claims.

This invention relates to improvements in fountain pens of the construction set forth in our co-pending patent application Serial No. 735,112, filed on July 14, 1934, and of which this application is a divisional application.

One of the main features of this invention resides in a fountain pen construction wherein the ink reservoir may be filled to its capacity upon each lling operation.

Another feature of the invention is the provision of a fountain pen in which the efficient ink filling means facilitates the use of a relatively small ink reservoir for an ample supply of ink, whereby the remainder of the length of the pen may be utilized for the compact storing of other articles, such as a shavers kit.

A further object of the invention is to provide a fountain pen having an ink sack normally held in an extended position within a barrel by a spring, but which sack may be compressed against the action of the spring by a manually operated tubular plunger, the plunger being xedly connected to the barrel when in retracted position to form an extension of the barrel and a storage compartment for a shavers kit.

With these and other objects in view, the invention resides in the novel construction, combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims and illustrated in the accompanying drawing, in Which:

Figure l is a side elevational View of the preferred embodiment of the invention.

Figure 2 is an enlarged vertical longitudinal sectional View on the line 2-2 of Figure 1.

Figure 3 is a horizontal sectional View on the line i-t of Figure l.

Figure 4 is a vertical sectional elevational view illustrating the manner by which the ink sack of the fountain. pen is filled.

Figure 5 is a fragmentary detail perspective View of the ink sack.

Referring to the drawing by reference characters, the numeral Ill designates a fountain pen which includes a cylindrical barrel I I, and threaded in one end of the barrel as at I2, is a collar I3 forming part of the nib section of the pen and into which collar the pen point I4 extends, and which is adapted to receive ink from a rubber ink sack I5, the open end of the sack I5 telescoping a reduced annular ange I6 at the inner side of the collar I3 and being ixedly secured thereto. Encircling the sack I5 is a coil spring I1, one end of which abuts the collar I3 while the other end of the spring extends through an opening in an ear I8 molded on the closed end of the sack I5. Thus it will be seen that the spring II tends to normally hold the sack I5 in an extended position, but permits of the compression of the sack for filling the same through the nib end of the pan in a manner to be presently explained.

Threaded into the barrel I I at that end thereof opposite to the end in which the collar I3 is threaded, is one end of a tubular holder I9, the threading connection between the holder and the barrel being designated atv20. The tubular holder I9 is open at its outer end and closed at its inner end, the closed end being provided with a concavity 2| to receive the closed rounded end of the sack i5 when the holder I9 is utilized as a plunger for compressing the sack I5 against the tension of the spring II. By screwing inwardly upon the tubular holder I9, the threaded connection between the holder and the barrel will be broken whereupon the closed end of the holder I9 may be utilized as a plunger for compressing the sack I5 in the manner shown in Figure 4 of the drawing. When the nib section of the pen is inserted intoa supply of ink and the sack I5 compressed in the manner just described, release of the holder I9 permits the spring I1 to return the sack and holder to a normal position, which at the same time creates a suction Within the sack suiicient to draw up a supply of ink therein. After a filling operation, the tubular holder I9 is again turned to effect the threaded connection 20 between the barrel I I and the said holder to assume the position shown in Figure 2 of the drawing.

Threaded to the nib end ofv the barrel II is a cap 22, the inner walls of which are tapered as at 23 to facilitate frictional engagement of the said wall with the outer open end of the tubular holder I9 as shown in Figure 4. This is the position of the cap when the nib end of the pen is exposed for use. The external diameter of the cap 22 is the same as the external diameter of the barrel II and carried by the cap' 22 is a clip 24, the ring portion 25 of which overlaps the open threaded end of the cap so as to overlie the joint between the cap 22 and the nib end of the barrel Il. The clip 2li is utilized for the fastening of the article to the wall of the pocket of the owner.

Stored within the tubular holder I9 is a shavers kit which includes a folding razor. 'I'he safety razor includes broadly a handle and a head. 'Ihe handle consists of a, cylindrical hollow section 26, the same being open at its outer end and closed at its inner end and of an external diameter to snugly slide into the tubular holder i9. Threaded to the lower open end of the handie section 26 is a lower handle section which comprises a casing 2l which may house an extendible shaving brush or other shaving requirement. The outer end of the casing 2 exteriorly thereof is provided with screw threads 29 for threading engagement with screw threads 3@ provided on the inside of the outer end of the tubular holder I9.

Having thus described the invention, what we claim as new and desire to secure by Letters Patent of the United States, is:-

1. A fountain pen comprising a barrel, a nib section at one end of said barrel, a rubber sack open at one end and having its open end Xed to said nib section, a coil spring surrounding said sack and having one end secured to the closed end thereof and its opposite end seated against said nib section, a plunger slidably mounted in the other end of said barrel, and a thread connection between said plunger and said barrel whereby said plunger may be normally held against sliding movement and unscrewed to facilitate inward sliding movement for compressing the rubber sack to draw a supply of ink thereinto through said nib section.

2. A fountain pen-comprising a barrel having a nib section at one end thereof, a rubber sack having its open end iXed to said nib section and extending within said barrel in spaced relation to the walls thereof, a coil spring surrounding said sack and having one end thereof seated against said nib section and its other end xedly attached to the closed end of said sack; a plunger slidably mounted in the other end of said barrel, and a detachable connection between said plunger and said barrel whereby said plunger may be normally held against sliding movement relative to said barrel and disconnected therefrom to facilitate free inward sliding movement for compressing said sack` toward the nib section, whereupon release of said plunger the spring will return said sack to extended position to draw a supply of ink therein.

3. A fountain pen comprising a barrel having a nib section at one end thereof, a rubber sack having its open end xed to said nib section and extending within said barrel in spaced relation to the walls thereof, a coil spring surrounding said sack and having one end seated against said nib section and its other end iixedly attached to the closed end of said sack, a plunger slidably mounted in the other end of said barrel, a concave seat provided in the inner end of said plunger, and a detachable connection between said plunger and said barrel whereby said plunger may be normally held against sliding movement relative to said barrel and disconnected therefrom to facilitate free inward sliding movement for compressing said sack toward the nib section, said concave seat engaging the closed end of said sack, whereupon release of said plunger the spring will return said sack to extended position to draw a supply of ink therein.

4. A fountain pen including a barrel having a nib section at one end thereof, a rubber sack having its open end Xed to said nib section and extending within said barrel in spaced relation to the Walls thereof, an ear formed integral with the closed end of said sack and eX- tending therefrom, a coil spring surrounding said sack and having one end seated against said nib section and its other end connected to said ear, a plunger slidably mounted in the other end of said barrel, and a detachable connection between said plunger and said barrel for noi'- mally holding said plunger against sliding movement and out of contacting engagement with the closed end of said sack.

5. In a fountain pen having a barrel and a nib section at one end thereof, an ink reservoir sack open at one end and closed at its opposite end, the open end of said sack being secured to said nib section and the said sack freely extending into said barrel, a coil spring surrounding said sack and having one end abutting said nib section and'its other end secured to the closed end of said sack, and .a member slidable lengthwise of said barrel and engageable with the closed end of said sack for collapsing the same against the tension of said spring.
